It will not be possible to effectively achieve the goals of the smart city without ensuring the security of this volume of data. Challenges such as data security, data privacy, data quality, data access, considering the interests of stakeholders at the same time and many other issues make it difficult to achieve smart city goals. In order to deal with these threats and also to reduce conflicts between security and Internet of Things services in Houshmand city, there is a need for "Internet of Things data security governance strategies in Houshmand city", which is presented as the main goal of the researcher in this research, and based on this, the researcher seeks to answer This question has been "What are the strategies of Internet of Things data security governance in the smart city?" After reviewing the national documents, the internal and external environment was recognized and analyzed, and based on the opinions of the experts, the relevant strategies were formulated, then they were prioritized based on the calculation of the benefits. Also, the impact of each of the mentioned strategies on the achievement of the goals was determined. These strategies are presented with the ability to be implemented and implemented in line with other areas, and by turning these strategies into executive plans and their implementation, and according to the data cycle in the smart city, the basic challenges of Internet of Things data security solved to an acceptable extent.

Smart cities rely heavily on technology and data to improve citizens' quality of life. However, this reliance on technology also creates significant security challenges such as cyber security threats, data privacy, interoperability and lack of necessary standards. In order to deal with these challenges and also to reduce conflicts between security and Internet of Things services in the smart city, it is necessary to consider initiatives. Data security governance is a process of ensuring data security while maintaining the efficiency and performance of the data in the areas of use. In order to use the data security governance of the Internet of Things in Houshmand city, it is necessary to identify its application areas. These areas can be calculated by considering the structure of the smart city, the Internet of Things, the structure and topic of data, as well as the beneficiaries of the data in the smart city. In this article, by studying different sources and using elite capacity, 4 main areas and 17 applied sub-areas of Internet of Things security governance in Houshmand city have been identified. Also, after identifying the areas, the effective factors on data security governance of Internet of Things in Houshmand city have been calculated.

Command and control system includes a variety of computer and communications equipment that is used to facilitate decision-making and management of the theater. In this system, the process of collecting, processing and continuous dissemination of environmental information and establishing and maintaining communication between members is of great importance. This information provides a good picture for the command to organize, direct, coordinate and control the forces. Because of the vitality and sensitivity of this information, fast, accurate, and transparent transfer of commands down the control chain and vice versa requires a secure and reliable infrastructure. The use of new technologies such as blockchain can solve many security risks and challenges of this system. A blockchain is a decentralized database that ensures information security in an insecure environment using advanced encryption. In this article, while reviewing this emerging technology, its role in providing security and accelerating the execution of command and control missions is examined. The findings of this study show that this technology, with its advantages such as speed in identifying objectives, the possibility of simultaneously pursuing all objectives, processing, integrating and displaying information, rapid and automatic information exchange, can reduce operational error, high reliability, fast response And reduce delays and interruptions in command and control systems.

One of the problems of educational systems is the subject of academic failure that have unpleasant financially and attitude result on the students and their family. This study examined the training effectiveness of group counseling cognitive therapy & reality therapy on reducing educational failure on the orphan students among the school students.
This research is an experimental study with a pretest and posttest and control groups were tested. Independent variable counseling cognitive therapy & realty therapy and dependent variable are educational failure. The population of study included all students who have educational failure in high school students in Saqqez city who have a bad family. Using a randomly selected sample of 45 and randomly in three groups of experimental and control. Experimental group for 8 sessions (1/30) hour training session cognitive therapy & realty therapy received every week of training and testing took about 2 months. The data collected by average score in formative and final. To show the difference between groups, were calculated the mean and standard deviation for the experimental and control group and Analysis of milt covariance was used for data analysis.
The results showed that cognitive and reality therapy had a significant impact on developmental scores and the second, orphan and irresponsible girl.
Cognitive and reality therapy has an effect on reducing orphan and irresponsible girl student.
